具体实施方式
此处描述了用于产生相对低速度脉动喷淋的淋浴头的实施方式。淋浴头可包括喷射盘、涡轮、遮板、和壳体。流经淋浴头的水促使涡轮旋转。随着涡轮旋转,它使遮板转动。遮板可被构造成以比涡轮更慢的速度转动以引起流经在壳体中所限定的或附接到壳体的出口或喷口的水的定期中断以产生脉动喷淋。该脉动喷淋可模拟手按摩的感觉。 
遮板可采取包括齿轮齿的大体上圆盘的形式,所述齿轮齿选择性地与在壳体中的相对的齿轮齿接合。涡轮可包括偏心凸轮,该偏心凸轮驱动遮板。所实现的减速是在壳体上的齿轮齿的数量和在遮板上的齿轮齿的数量之间的差与在遮板上的齿轮齿的数量的比率。在数学上表达,这可书写为:(壳体齿-遮板齿)/(遮板齿)。 
图1-15描绘淋浴头100的第一实施例的各个视图。参考图1和2,淋浴头100可包括壳体102。壳体102可由上壳体部104和下壳体部106形成。上壳体部104可包括用于接纳来自流体源的流体的流体进口。上壳体部104还可包括螺纹108,该螺纹108靠近流体进口用于将淋浴头100螺纹连结到流体源,该流体源例如淋浴管、柔性臂、软管连接器、臂组件、或用于将诸如水的流体(即,流体源)输送到淋浴头100的其它装置。虽然被示出为螺纹连结到流体输送装置,但是淋浴头100可使用任何已知的连接方法或方法的组合附接到流体输送装置,所述连接方法包括但不限于压入配合、夹紧、焊接、等等。下壳体部106可包括一个或多个与流体进口选择性地流体连通的流体出口110。流体出口110可以是大体上圆孔或任何其它适当地成形的孔或开口。诸如水的流体可从流体源经由淋浴头100通过流体出口110中的至少一个输送到用户。 
上壳体部104、下壳体部106或两个部可包括用户接合特征以便于连结这些部。例如,如图1和图2中所示的上部分104和下部分106各自可包括凹进表面112、114用于为用户提供用以抓握的表面。在其它实施例中,上壳体部104、下壳体部106或两者可合并其它类型的用户接合特征或特征的组合,诸如抬升的突起部、耳片、隆起、粗糙化表面等,从而可促进用户在上壳体部104、下壳体部106、或两个部分上的抓握,以便连结这些部、相对淋浴管或用于将流体输送至淋浴头的其它装置移动淋浴头100、和/或选择淋浴头运行模式。 
转向图3-5,上壳体部104可包括限定了流体通道的大体上圆筒形壳体轴116。流体通道可与流体进口流体连通。大体上环状壳体凸缘118可从壳体轴116的下部部分径向向外延伸。大体上圆形的上壳体侧壁120可从壳体凸缘118大体上向下延伸。上壳体侧壁120的内表面可包括用于将上壳体部104连结到下壳体部106的螺纹。如本领域已知的限流器(未示出)可定位在流体通道中以限制流体从流体地连接的流体源流经淋浴头100。 
下壳体部106可包括大体上圆形的下壳体基座122。大体上圆形的下壳体侧壁124可从下壳体基座122向上延伸。下壳体侧壁124的外表面可包括被构造成接合上壳体螺纹的螺纹。 
上壳体螺纹和下壳体螺纹可接合以将上壳体部104连结到下壳体部106。虽然上壳体螺纹被示出为内部螺纹并且下壳体螺纹被示出为外螺纹,但是上壳体螺纹可以是外螺纹并且下壳体螺纹可以是内螺纹。此外,上壳体部104和下壳体部106可通过任何已知的连接方法来连结,所述连接方法包括但不限于压入配合、夹紧、焊接、前述的螺纹连结等。 
上壳体部104和下壳体部106可限定室或腔126。室或腔126可由上壳体凸缘118、下壳体侧壁124、和下壳体基座122限定。室或腔126在形状上可以是大体上圆筒形或任何其它期望的形状。室或腔126可与上壳体流体通道流体连通并且与流体出口110选择性流体连通。 
虽然上壳体部104和下壳体部106的形状和构造被描述且示出为具有某种特定性,但是上壳体部104和下壳体部106可采取任何期望的形状以限定壳体102的外部和内部。此外,壳体102可由多于或少于两个壳体部形成。然而,虽然壳体102被示出为包括一个流体进口、一个流体通道、和一个室或腔,但是该壳体可包括或限定多于一个的这些元件中的任何元件。例如,壳体102可限定两个流体进口、两个流体通道、和/或两个室或腔。前述示例仅仅是说明性的并且不旨在针对壳体102暗示任何特定数量或布置的流体进口、流体通道、或室或腔。 
继续参照图3-5,淋浴头100还可包括喷射盘130、涡轮132、遮板134、以及一个或多个密封构件136,138。喷射盘130、涡轮132、和遮板134可被接纳在由壳体102限定的腔或室126内。流体源密封构件136可定位在上壳体部104的流体进口内,并且壳体密封构件138可定位在上壳体部104和下壳体部106之间靠近这些部被连结的区域。 
喷射盘130可包括大体上圆形且平的本体或任何其它适当地成形的本体。喷射盘130可包括一个或多个喷射盘流体喷口或开口140。虽然在图4和图5中示出了三个喷口140,但是喷射盘130可包括多于或少于三个喷口。每个喷口130可从喷射盘130的上表面142延伸到下表面144,从而创建让流体从喷射盘的上表面142流至其下表面144的路径。此外,喷口140可相对于喷射盘的上表面142和下表面144倾斜以对经过它们的流体给予定向流动。这样的定向流动可促使涡轮132在淋浴头腔126内转动。喷口140也可被覆盖,这可增加流体的流速。替代实施例可改变所利用的喷口140的数量和/或覆盖构造。 
涡轮132可采取大体上中空开放端的筒的形式,并且叶片146从大体上圆形的涡轮壁150朝中央毂148径向向内延伸。在一些实施例中可省略涡轮壁150或涡轮壁150的至少一部分。此外,叶片146的数量可多于或少于图中所描绘的数量。涡轮132可包括从其上侧大体上向上延伸的第一销形突起部152和从其下侧大体上向下延伸的第二销形突起部154。每个销形突起部152、154可被定位成沿着涡轮132的中心轴线。下销形突起部154可被接纳在壳体102中的开口156中,并且上销形突起部152可被接纳在喷射盘130中的开口158中。涡轮132可绕其中心轴线(即,绕销形突起部152,54)转动。可替代地,涡轮132可具有:上开口,其接纳从喷射盘130的下侧延伸的销形突起部;以及下开口,其接纳从壳体102延伸的销形突起部。涡轮132可包括在其下侧(即,面对遮板134的一侧)上的偏心凸轮160。 
遮板134可采取大体上圆形且平的本体或任何其它期望的形状,并且可包括沿着其中心轴线的开口162以接纳偏心凸轮160。随着涡轮132转动,遮板134可因此绕偏心凸轮160的中心轴线旋转。偏心凸轮160的中心相对于涡轮132和壳体102的中心轴线是偏心的。因此,随着涡轮132旋转,偏心凸轮160使遮板134的中心以大体上圆形路径环绕涡轮132和壳体102的中心轴线移动。随着遮板134的中心以该大体上圆形路径移动,其周边的接合或以其它方式接触下壳体部的侧壁124的部分改变,如例如图7-15中所示。 
遮板本体164可包括一个或多个贯穿其厚度的流体开口166、168以便水从遮板134的上侧170传递到下侧172。遮板流体开口166、168可选择性地与在壳体102中的出口110中的至少一些对准。当对准时,水或其它流体可从壳体室或腔126流动以及从与遮板流体开口166、168对准的出口110流出。遮板34可包括接合特征74,其可采取齿轮齿等的形式。齿轮齿可以、但是不必、环绕遮板本体的周边均匀地分布。 
壳体102可包括壳体接合特征176以接合遮板的接合特征174。壳体接合特征176可以是与遮板的齿轮齿174互补的接合齿。例如,壳体接合特征176可由带有凹陷部的圆形凹进区域限定在下壳体106的上表面222中,且凹陷部具有与遮板134的接合特征174的齿轮齿互补的形状。这些可以、但不必、等间隔地环绕下壳体部106的内部周边。如例如图7中所示,遮板134可包括十五个齿轮齿,并且壳体102可包括十六个壳体齿。其它实施例可针对遮板134和/或壳体102使用不同数量的齿轮齿。遮板的齿轮齿174的至少一些可接合壳体的齿轮齿176。此外,随着涡轮132转动,遮板134的接合壳体102的齿轮齿176的齿轮齿174可改变。 
返回图3-5,流体源密封构件136可在淋浴头100和连结到淋浴头100的流体源之间形成流体密封。更具体地,流体源密封构件136可大体上限制或以其它方式防止流体从淋浴头100沿着将该流体源连结到淋浴头100的螺纹接头泄漏。壳体密封构件138可在上壳体部104和下壳体部106之间形成流体密封以基本上限制或以其它方式防止流体从淋浴头100沿着将上壳体部104连结到下壳体部106的螺纹接头泄漏。流体源和壳体密封构件136、138可采取O型环的形式或在两个或更多个构件或部件之间提供流体密封的任何其它适当的元件,并且可由诸如橡胶的弹性材料或任何其它已知的流体密封材料构成。 
现在将参照图3、图6和图7来描述淋浴头100的运行。水或其它流体可从流体源流经流体进口到喷射盘130。随着水或其它流体经过喷口140,它冲击涡轮132的一个或多个叶片146,该涡轮132位于在遮板134和喷射盘130之间的壳体102内。水冲击涡轮叶片146对涡轮132给予转动运动。如从涡轮132的面对如例如图6中所示的遮板134的一侧所观察到的,涡轮132可以顺时针方式转动。替代实施例可促使涡轮132以逆时针方向方式转动。在冲击涡轮叶片146之后,水撞击遮板134的上侧170。 
随着涡轮132因水冲击其叶片146而转动,涡轮132促使遮板134的中心经由在遮板134和涡轮的偏心凸轮160之间的前述连接以大体上圆周运动移动。这使得遮板134的外齿中的至少一些与壳体102的内齿中的一些啮合,导致遮板134相对于涡轮132的转动运动。另外,遮板134和壳体102的齿在遮板134的近似与如例如图7和图12-15中所示的接合点相对的一侧脱离。 
由于遮板134的齿比壳体102的齿少一个,并且使得在遮板134和壳体102之间的齿脱离可通过遮板134的中心以环绕涡轮132的中心轴线的大体上圆形路径运动,所以涡轮132的每一整圈导致遮板134相对于壳体102的一个齿移位。该移位是在与涡轮132的转动相反的方向上。例如,如果涡轮132沿顺时针方向转动,则遮板134相对于壳体102的一个齿移位将在逆时针方向上,并且反之亦然。遮板齿与壳体齿的该选择性接合起到减速机构的作用,因为遮板134以与其将缺少该接合时速度的1/15旋转。因此,涡轮132、凸轮160、遮板134和壳体102的组合作为摆线驱动器一起运行以实现从涡轮132到遮板134的转动速度减小。 
所实现的减速(即,遮板134转动多快相对于涡轮132转动多快)通过壳体102的接合特征176的数量和在遮板134上的接合特征174的数量之差与在遮板134上的接合特征174的数量的比率来确定。对于图1-15中所描绘的淋浴头,由于壳体102具有十六个齿轮齿,并且遮板134具有十五个齿轮齿,所以产生1/15的减速。即,遮板134以涡轮132的转动速度的1/15转动。 
在其它实施例中,遮板可具有30个齿轮齿,并且壳体可具有31个齿轮齿。这促使遮板以涡轮的转动速率的1/30沿涡轮的相反方向翻转。换言之,每次涡轮完成一转,遮板绕其中心轴线转动近似1/30转,并且遮板沿涡轮的相反方向转动。因此,每次涡轮完成30转,遮板沿涡轮的相反方向完成一整转。在例如图16中的淋浴头100'的其它实施例中,遮板134'可具有比壳体102'更多的接合齿,这促使遮板134'沿与涡轮132'相同的方向但是以较慢的速率转动。例如,图16的实施例使用带有30个接合特征174'(即,齿轮齿)的遮板134'和带有28个接合特征176(即,壳体齿)的壳体102'。这促使遮板134'进动即沿与涡轮132'相同的方向以涡轮132'的速度的1/14的速率翻转。其它实施例可利用带有更多或更少的齿的遮板和壳体来实现遮板相对于涡轮的转动速度和转动方向的期望的减速和转动方向。 
参照图8-12,随着遮板134在带有由壳体接合特征176限定的凹进区域的壳体102内转动,在遮板134中的一个或多个遮板流体开口166、168越过布置在由通过壳体接合特征176限定的凹进区域中的出口110排。以这种方式,水可临时地流经位于遮板流体开口166、168的下方的无障碍的出口110。因此,随着遮板134转动,通过出口110的水流定期地被中断,因为遮板134的实心部分临时地阻碍通过位于遮板134的实心部分下方的出口110的水流,如例如图8-12中描绘。这产生水从淋浴头100的脉动流动。脉动流动的周期部分地通过如下文进一步解释的遮板134的转动速度来确定。 
图9大体上描绘在涡轮132已经沿逆时针方向完成一个整转之后遮板134从在图8中占据的相对位置在壳体102内沿顺时针转动。图10大体上描绘在涡轮132已经沿逆时针方向完成两个整转之后遮板134从在图8中占据的相对位置在壳体102内沿顺时针转动。图11大体上描绘在涡轮132已经沿逆时针方向完成三个整转之后遮板134从在图8中占据的相对位置在壳体102内沿顺时针转动。 
参照图8-12,遮板134可具有内流体开口166和外流体开口168,该内流体开口166和外流体开口168各自环绕遮板134延伸约一半。内流体开口166和外流体开口168可大体上形成在遮板134的相对的半部上。壳体102还可包括内、外圆形出口110排。遮板的内流体开口168可重叠内圆形出口110排的至少一部分,而外流体开口166可重叠外圆形出口110排的至少一部分。当遮板流体开口166、168位于某些出口110的上方时,水流经这些无障碍的出口110以离开淋浴头100。当出口110与遮板流体开口166、168中的至少一个不对准时,水流被阻挡通过该出口110。因此,随着遮板134转动,通过出口110的水流可按顺序地被中断。这可例如引起通过每个出口110排的水流的相对低速的定期中断。 
如先前所讨论的,对于图1-15中描绘的实施例,在遮板134上存在15个齿轮齿并且在壳体102中存在16个齿轮齿,使遮板134以涡轮132的速率的1/15的速率沿与涡轮132相反的方向转动。水通过出口110的脉动流动的周期是减速与涡轮速度的直接相乘。因此,如果通过淋浴头100的水流促使涡轮132以60转/秒旋转,则遮板134将以4转/秒的速率转动。这导致通过出口110的脉动流的周期为约0.25秒,这可模拟手按摩的感觉。作为另一示例,如果涡轮132以50转/秒转动并且减速是1/10,则遮板134将以五转/秒的速率转动。这导致通过出口110的脉动流的周期为约0.20秒。前述示例仅仅只是说明性的并且不旨在暗示或需要特定减速、涡轮速度、或脉冲时间。 
前述脉冲时间代表流经出口110的一个完整循环的时间段。换言之,水开始流经出口110、停止流经出口110、然后再次开始流经出口110所花费的时间。在单循环期间水流经和不流经出口的时间量的比率是遮板流体开口的长度的函数。随着遮板流体开口的长度增加,水流经相关联的出口110的时间与它不流经出口110的时间的比率增加。例如,如果遮板流体开口的长度延伸遮板134的圆周的近似一半,如例如图7-15中所示,则水流经出口110的时间与不流经出口110的时间的比率将为近似1:1。作为另一示例,如果遮板流体开口的长度延伸遮板134的圆周的近似四分之一,则水流经出口110的时间与不流经出口110的时间的比率将为近似1:3。前述示例仅仅是说明性的并且不旨在暗示任何特定长度或在淋浴头的单循环期间的流动时间的比率。 
图16-25描绘淋浴头200的第二实施例的各个视图。第二淋浴头200在结构和运行上与第一淋浴头100类似,并且用于第二淋浴头200的类似的标记可用于第一淋浴头100的类似或相似的元件。像第一淋浴头100那样,第二淋浴头200可包括涡轮132、喷射盘130、遮板134、和壳体102。在该特定实施例中,遮板134可包括环绕遮板134延伸约三分之二的一个流体开口202,如例如图19-20中所示。淋浴头200还可包括一个或多个密封构件136、138,诸如流体进口密封构件136和壳体密封构件138,如例如图18-20中所示。流体进口密封构件136和壳体密封构件138可类似于针对第一淋浴头100所描述的对应的密封构件136、138。 
像第一实施例那样,第二淋浴头200的壳体102可包括上壳体部104和下壳体部106,其如例如图18中所示的螺纹连结或通过任何其它已知的连接方法或其组合连结。另外,像第一淋浴头100的壳体102那样,第二淋浴头200的壳体102虽然在图中被示出为具有特定的形状,但是可被形成为任何期望的形状并且可由任何期望数量的部分或部件形成。壳体102可包括如图20中所示的一排出口或喷口110,其可经由在下壳体部106的基座122中限定的流体通道或导管204流体地连接到壳体室或腔126,如例如图18和19中所示。基座122可被形成为在下壳体部106的上表面222的凹进区域下方的独立层或由所述凹进区域形成。凹进区域可由具有圆形凹进区域的壳体接合特征176限定,且圆形凹进区域的凹陷部具有与遮板134的接合特征互补的形状。每个流体通道204继而可包括图23中所示的流体通道开口206,该流体通道开口206在下壳体部106的上表面222中例如在由壳体接合特征176形成的凹进区域中的中被限定,用于将流体通道204流体地连结到壳体室或腔126。与前一个实施例一样,图25中所示的涡轮132可采取大体上中空开放端的筒的形式,且叶片从大体上圆形涡轮壁朝中央毂径向向内延伸。对于给定大小的涡轮132和/或室126,流体通道204允许使用更大的淋浴头200来产生从淋浴头200的更大直径的喷射形式。 
像第一淋浴头100的遮板134那样,图24中所示的第二淋浴头200的遮板134可包括大体上圆形且平的(或任何其它形状的)本体,该本体包括至少一个遮板流体开口202。另外,像第一淋浴头100的遮板134那样,第二淋浴头200的遮板134可包括沿着其中心轴线用于接纳形成在涡轮132上的偏心凸轮160的凸轮开口162。随着涡轮132转动,遮板134可因此以类似于第一淋浴头100的遮板134的方式绕偏心凸轮160的中心轴线旋转或转动。随着涡轮132旋转,偏心凸轮160的运动促使遮板134绕偏心凸轮60的中心转动,使得遮板周边的接触壳体102的部分改变,如以上针对第一淋浴头100更详细地描述的。 
遮板134和壳体102可各自包括一个或多个齿轮齿,如上所述。例如,如图21和图22所示,遮板134可具有15个齿轮齿,并且壳体可具有与这些遮板齿接合的16个齿轮齿。因此,遮板134相对于涡轮132沿相反的方向以涡轮132的速度的1/15的速率在壳体102内转动。图22大体上描绘遮板134从其在图21中的位置在壳体102内顺时针转动。 
如图21和图22中所描绘,随着遮板134在上表面222的上方例如由壳体接合特征176限定的凹进区域内转动,通过流体通道开口206并且因此布置在基座122中且在与相应的流体通道开口206流体连通的凹进区域中的出口110的水流被中断,因为遮板134的实心部分经过流体通道开口206。当遮板流体开口202在流体通道开口206的上方时,水流经相关联的流体通道204并且通过与流体通道204相关联的出口110离开淋浴头200。当流体通道开口206与遮板流体开口202不对准时,水流停止通过与流体通道开口206流体连通的出口110。因此,随着遮板134转动,流经出口110的水可按顺序地被中断。这可例如引起通过每个出口110的水流的相对低速的定期中断。其它实施例可在壳体102中利用更多或更少的出口110排并且可利用更多或更少的遮板流体开口202以创建各种低速脉动水流模式。例如,多个遮板流体开口202可彼此径向对准以产生喷射模式。作为另一示例,出口110在上壳体基座122上的一个或多个节段内被分组和/或在一排或多排内被非均匀地隔开。 
通过第二淋浴头200至少到遮板134的下侧的水流大体上按先前在上文中针对第一淋浴头100所描述的前进。另外,如先前在上文中针对第一淋浴头100所描述的,遮板接合特征174与壳体接合特征176的选择性的接合,促使遮板134以比涡轮132更慢的速度转动,其中壳体接合特征176由具有凹陷部的圆形凹进区域限定,该凹陷部具有与下壳体106的上表面222中的遮板接合特征174互补的形状。随着遮板134在壳体102的室126内转动,一个或多个遮板流体开口202可越过在下壳体106中的一排或多排流体通道开口206。这允许水临时地流经无障碍的流体通道开口206。因此,随着遮板134转动,通过出口或喷口110的水流定期地被中断,因为遮板134实心部分临时地阻碍通过与位于遮板134的实心部分下方的流体通道开口206流体连通的那些出口110的水流。这产生水从淋浴头200的脉动流动。 
第二淋浴头200的各实施例对于流体通道开口206到出口或喷口110可使用相同或不同的数量。例如,每个出口110可与单个流体通道开口206流体连通,或出口110可与两个或更多个流体通道开口206流体连通,或反之亦然。 
淋浴头的其它实施例,包括第一淋浴头100和第二淋浴头200的变型,可使用在遮板134和壳体102上的其它类型的可接合特征以促使遮板134以与涡轮132不同的速率转动。例如,遮板134可具有外渐开线齿,并且壳体102可具有匹配的内渐开线壳体齿。作为另一示例,遮板134可具有与在壳体102中的锯齿切口相匹配的锯齿特征,如图26和图27中所描绘的。在又一示例中,从遮板134的周边径向延伸的销可与在壳体102中的槽相匹配。如又一示例,在遮板134中的槽可与从壳体102径向向内延伸的销相匹配。如再一示例,在遮板134的周边中的圆形切口可接合在壳体102中的销。前述例子仅仅是说明性的并且不旨在将遮板134和/或壳体102的可接合特征限制于任何特定的特征,或不旨在限制用于促使遮板134以与涡轮132不同的速率转动的其它机构。 
此外,遮板134到壳体102的接合总体上不限制到对接合特征174、176的使用来实现减速机制或以其他方式改变遮板134相对于涡轮132的转动速度。在一些实施例中,可通过遮板134和壳体102之间的摩擦接合使遮板134落后于涡轮132。在这类实施例中,减速可通过壳体102和遮板134的直径差除以遮板134的直径的比率来确定(假设小到在遮板134和壳体102之间无滑动)。 
图28-31描绘随淋浴头100、200中的一个或两个使用的下壳体106和遮板134的替代实施例的各个视图。为了简单化的目的,淋浴头的不同于下壳体106和遮板34的元件未在图28-31中描绘。应了解,省略的元件可被构造成与先前实施例的淋浴头的相同部件基本上完全相同。 
参照图29,在该实施例中,一个或多个流体通道开口206和环状凹部226可限定在下壳体部106的上表面222上。环状凹部226可由外部侧壁224和内部侧壁225限定,内部侧壁225限定了销接纳构件227的周边。销接纳构件227可限定用于接纳下销形突起部154的开口156。环状凹部226的大小设计成并成形为容纳遮板134的互补的部分。 
在本实施例中,下壳体部106的接合特征176可限定环状凹部226并且相对于流体通道开口206径向向内地定位。例如,接合特征176可被设置在外部侧壁224上。本实施例的接合特征176相对于流体通道开口206的定位与前一个实施例相反,在前一个实施例中,接合特征176相对于流体通道206径向向外地定位,导致流体通道206布置在由这些接合特征限定的凹进区域内。因此,在该实施例中,流体通道开口被限定在下壳体106的上表面222中,但是不在环状凹部226内。 
以本实施例的方式对接合特征176的构造例如提供更加紧凑的淋浴头以及在腔126内的由上壳体部104和下壳体部106形成的更加有效的使用空间。与前一个实施例一样,接合特征176可被形成为接合齿用于接合遮板134的互补的齿轮齿。与前一个实施例一样,下壳体部106可进一步包括适当的接合特征以便于将下壳体部106连结到上壳体部104,例如被构造成接合上壳体部104的互补的螺纹的螺纹。 
特别参照图30-31,根据本实施例,遮板134可采取包括上遮板部236和下遮板部238的多平面的本体的形式。上遮板部236和下遮板部238可一体化地形成或可由两个通过适当的紧固机构紧固到彼此的独立部件制成。与前一个实施例一样,遮板134可包括沿着其中心轴线用以接纳偏心凸轮160的开口162。随着涡轮132转动,遮板134可因此绕偏心凸轮160的中心轴线旋转。如相对于先前实施例所讨论,偏心凸轮160的中心相对于涡轮132和壳体102的中心轴线可以是偏心的。因此,随着涡轮132旋转,偏心凸轮160使遮板134的中心以大体上偏心圆形路径环绕下壳体106和涡轮132的中心轴线移动。随着遮板134的中心以该大体上偏心圆形路径移动,下遮板部238的周边的接合或以其它方式接触环状凹部226的侧壁224的部分改变。 
上遮板部236可采取轴向地设置在下遮板部238的上方的大体上平面本体形式并且限定一个或多个流体阻碍构件240。一般而言,流体阻碍构件240可被构造使得当遮板134适当地坐置在环状凹部226中时,流体阻碍构件240在上表面222的上方延伸,使得它们基本上限制或以其它方式防止流体流入到流体通道开口206中的一个或多个中,而允许流体流入到其余流体通道开口206。如所示出的,单个流体阻碍构件240可被形成为径向延伸部,其延伸超过下遮板部238的周边。流体阻碍构件240可绕上遮板部236周向地延伸近似上遮板部236的三分之一。可替代地,任何数量的周向地延伸达遮板134的任何期望部分的流体阻碍构件240可被利用。在进一步的替代方案中,流体阻碍构件240可以任何方式成形为适合于选择性地限流到流体通道开口206中的一个或多个中。在进一步的替代方案中,流体阻碍构件240可包括贯穿它们的厚度的一个或多个开口用于允许流体从中经过。 
下遮板部238的尺寸设计并成形为可转动地容纳在下壳体部106的凹部226中。例如,如图31中所示,下遮板部238可被形成为环状且平面的本体,该本体具有设置在其周边表面上的接合特征174。接合特征174可例如形成为与下壳体部106的接合特征176互补的齿轮齿。与先前实施例一样,下壳体106的接合特征176的数量可多于遮板134的接合特征174的数量。下遮板部238可进一步包括限定环状凹部243的内部侧壁241。环状凹部243的尺寸设计并成形为由销接纳构件227接纳,使得遮板134相对于下壳体部106自由地偏心转动。就这点而言,环状凹部243的直径可大于销接纳构件227的外直径以适应遮板134的偏心移动。在一个实施例中,下遮板部238可竖直地定尺寸,使得当它坐置在下壳体106的凹部226中时,下遮板部238的顶表面239和上遮板部236的底表面246位于基本上对应于下壳体部106的上表面222的平面中。 
在本实施例的操作中,当阻碍构件240通过流体通道开口206的上方时,通过流体通道开口206的水流可被中断。与先前实施例相反,到流体通道开口206的水流不通过在遮板234限定的开口实现,而是因为上遮板部236的阻碍构件240未完全延伸环绕下遮板部238的周边而实现。当阻碍构件240不在流体通道开口206的上方时,水流经相关联的流体通道204并且通过与流体通道204相关联的出口110离开淋浴头。当流体通道开口206与阻碍构件240对准时,水流停止通过与流体通道开口206流体连通的出口110。因此,随着遮板134转动,流经出口110的水可按顺序地被中断。这可例如引起通过每个出口110的水流的相对低速的定期中断。 
如先前相对于淋浴头100、200所描述的,遮板接合特征174与壳体接合特征176的选择性接合促使遮板134以比涡轮132更慢的速度转动。随着遮板134在下壳体106内转动,阻碍构件240可越过在下壳体106中的一个或多个流体通道开口206。这可允许水临时地流经未被阻碍的流体通道开口206。因此,随着遮板134转动,通过出口或喷嘴110的水流定期地被中断,因为遮板134的阻碍构件240临时地阻碍水流经与位于阻碍构件240下方的流体通道开口206流体连通的那些出口110。这可例如产生来自本实施例的淋浴头的水的脉动流动。
